Your Questions About Wind Turbines Colorado
Laura asks…
Should the brightest mind in the world be focusing on solving the pollution problems?
With all the health issue’s tied to smog and the eviromental impact from smog, Shouldn’t we be making this the highest priority to fix? Many of you may not know about the seriousness of the pollution from coal burning plants and we have solutions to fix it but it is moving slow also the burning of petroleum fuels should be fazed out the sooner the better because they just can’t be made clean. All this pollution ends up in the ditches then streams then rivers and lakes and it doesn’t have to be that way. If we have the solutions then why not move on to the future and live in a cleaner world?
admin answers:
There are many very brilliant people working on many different aspects of “green” technology. Solar energy and biofuel research has been going on since the ’70s (although poorly funded from mid ’90s till recently). There is a national lab dedicated to renewable energy in Colorado (www.nrel.gov) and other national labs like Sandia and Oak Ridge also do research related to greentech.
There is also a very large new center opening at Berkeley called the “Energy Biosciences Institute” which is partially funded by BP. Contrary to the previous response, ignoring the environment is only in the short-term interests of corporations. In the long term, even they need to be concerned about the problems that have been building, and some of those with more forsight are beginning to take the lead in putting more capital behind greentech – it is in fact, a great business opportunity.
The problem is that solving these problems isn’t like a moon-shot. We can’t put tons of resources into a single program and expect it to find “the answer” to pollution. We need renewable plastics, green chemistry, improved agriculture practices, biofuels, thin-film solar, blades for wind turbines, more efficient engines/turbines, lightweight materials, redesigned transportation infrastructure, better power grids, eco-friendly architecture, AND ways to retrofit all the fancy new stuff into our current reality.
Maria asks…
Do you think all new build houses should have solar panels fitted?
Don’t you think it would be a good idea if the Government made it compulsory to have all new build houses fitted with solar panels? If everyone had solar panels, the price of them would come right down.
What do you think?
admin answers:
No.
Simply, not every house will be a compatible match for solar.
Solar needs sunlight. If a roof surface is not in the correct 40 degree sun path facing magnetic south, then modifications have to be made to build up and angle panels so they do. This can cost more than the energy ever produced for the home. That is an unfair burden to add those costs to that homeowner. The ideal home will face south with a 40 degree pitch to the roof. Can you imagine every house from here forward with a plain gable roof all faced south?
In addition, trees could become an obstruction. Planting designs would have to eliminate any tree that would grow higher than roofline and shade the panel array. Passive solar methods like tree lines have been used for years to help summer cooling costs.
Geothermal systems are working very well in Colorado which suffers severe weather mood swings between hot and cold. A new energy efficient home built in the foot hills just proved its capabilities. The annual heating costs for this 2000 sq foot home was $34.00. Yes, $34.00 for the entire year. That system also heats the water used to bathe and shower in.
The cost of that system paid for itself in the first 2 years making this one of the best investments on the market. I say skip the stock market! Homes, including those in the City, can be designed with either a horizontal or vertical system.
Eastern Colorado is finding great success with small wind turbines making them more affordable than a typical solar panel array.
At this point, no, I don’t see this becoming a mandatory situation. But, the solar manufacturers have been supported and are working for grid autonomy meaning the panels should be as cost effective to install as hooking up to your local power. The solar industry knows it has to become more competitive. It’s very survival depends on it and we are already seeing drops in pricing.
Let me point out that Solar is still a good return on investment “for the right house”.
The energy efficiency approach is based on Best Practice. That means, one system like solar will not work as the solution for everyone. Building codes like plumbing and sanitary systems are because of safety and health reasons but they dont mandate this product or that product. Just that the products must be safety tested to meet certain standards. They do mandate that solar follow NFPA and NEC codes (National Fire Protection Association and National Electric Code) and be installed by a Master Electrician… Again for safety reasons. Geothermal be installed by a licensed Master HVAC and a Certified driller. For, you got it, safety reasons.

Your Questions About Wind Turbine Generators For Home
David asks…
How much power is required to power a large family home?
I am doing some research into setting up a wind turbine for my house. I see terms like ‘kW hours’ for energy or power consumption. If my house uses 1500kW hours of energy per week does this mean i need to run a 1500kW generator for 1 hour to satisfy my power needs?
How would i then go about sizing the required turbine needed to effectively power my home?
This is all new to me so i can see alot of follow up questions coming/
admin answers:
In terms of system design, you need to consider the load imposed on the supply. In your question you mentioned a figure of 1500 kWh per week. This seems very high. It represents an average of 35 amps being drawn from the supply 24/7.
I have a 4 bedroom house occupied by 2 adults and the minimum load, during the night falls to 0.8 Amps and peaks on some days to around 18 Amps for very short periods, the average through the day is about 2 Amps.
One kW represents a load on the supply of about 4 amps for 240 volt supplies and about 8 on 120 volt supplies Understanding the load that is being imposed on the supply will help you to decide the dimensions of the system you need.
For local power generation (micro generation) you can use wind or water turbines dependant upon location, and you can also use peizo electric generation (solar cells), all these are referred to as primary power. In addition to this you will need storage which is in the form of batteries.
To use the battery power you will need an inverter, which generates power at mains voltage from the low voltage batteries. Additionally you will need a regulator, which controls the charge/discharge of the batteries, and is essential for efficient battery use and economical battery life.
If your system is capable of generating power surplus to your requirements, you can sell this to your grid supplier for quite a reasonable return.
Paul asks…
Is it true that wind turbines can never produce enough energy in their lifespans to offset its creation?
I’ve heard on several occasions that wind turbines are not economically feasible because it takes an inordinate amount of time and money, such that it will never produce enough energy to recoup that which was lost in building the turbine. Is this true? Can anyone give me a source?
admin answers:
Hey Patrick, this concept has been around since about 1998 when it first surfaced in regard to solar panels. There was a lot of complaints that solar panels never earn back their, “Embodied Energy,” which is a phrase referring to how much energy it takes to mine raw materials, ship them to a factory, build the product, ship it to it’s destination and install it. To be honest, it is difficult to put an exact energy price on something like that, there are almost limitless variables, such as which mine was used, where it was shipped, how it is installed and used in the end, and so on. A non profit group called, Solar Energy International finally offered some grants to a few colleges to research this. In the end, they couldn’t come up with an exact timeline, but a range based on the above variables.
First of all, solar panels actually do repay their embodied energy some time between 1.5 and 6 years after they are installed. Virtually all manufacturers warranty their product to last at least 25 years, and typically they operate well beyond this time. Similar work was done later with wind turbines, and the results are very similar. The main difference being the range of payback time is wider, meaning it’s possible for a turbine to repay its embodied energy faster, like in less than a year, but it may take as long as 9 years. This is because shipping a utility sized wind turbine can take a huge bite into its embodied energy budget depending on how far it has to go. Solar panels can fit in the back seat of a good sized car, some wind turbines have specially designed hauling vehicles that might have to drive across the country, or across the street. But when you look deeper down this rabbit hole, you eventually learn that non of this matters, I’ll explain.
Electricity has been around since Thomas Edison nearly burned down his house running high amounts of current through bailing wires inside old mason jars, so it isn’t going away anytime soon. The question becomes, “What is the best way to produce it?” Let’s assume you build a 10 KW wind turbine, and put it alongside an efficient conventional power source, say a natural gas fired turbine 10 KW generator. Which will earn back its embodied energy faster? The answer is the gas generator never does. You have to remember that once you build a natural gas generator, coal plant, or any other non renewable energy based power plant, you now have to feed it fuel for the rest of it’s life. It’s conversion rate will always be something below 100%, so in the end it slowly digs itself a deeper and deeper energy hole that it can never crawl out of. At least the wind turbine has a chance to get even in it’s lifetime. This is the key to what makes renewable energy so great, it’s really the difference between buying a home and renting an apartment, one day the home will be paid off, the apartment never is.
We live in a home that is powered by the wind and sun today. About 12 years ago we started looking into solar and wind when our electricity was constantly going out. It began as a small backup plan, just to run a few lights and some electronics. Over time it became more of a hobby and lifestyle, like growing your own tomatoes instead of buying them at the store, we just grew electrons in our garden. Now our home generates over 90% of its own electricity, and we use the power company as our backup source. Even though it will take years to get even with the power bill, it’s worth it to us, and we’ve turned a lot of heads. Once each year now I am invited to the local schools to teach solar power to the 5th graders, then they run a field trip out to our house to see a working solar and wind powered home. Since then the power companies have been busy building wind farms and looking into solar, geothermal and biomass energy. They even have a methane plant alongside a landfill in the next county. Most people are not aware of these things, but they are happening. They are busy complaining about wind mills never earning back their manufacturing energy, solar being too expensive, or hybrid cars not really saving and gas. There is research on these subjects, and it’s available for the asking if you look for it online. My suggestion is you look into it and become better informed insteading of asking hacks like me online for advice. I’ll include some sources below. Hope this answers your question. Good luck Patrick, and take care, Rudydoo

Your Questions About Wind Generators For Sale
Mary asks…
How can I create high voltages at home?
Say in the range of about 5K volts?? What is the equipment required?
admin answers:
A generator? For real?
You don’t need a generator. You need a transformer. You need to know how much voltage you’ll be supplying it with, and you already know what voltage you need coming out of it. Transformers work on simple ratios. You have two sets of wire wound around each other. The magnetic field of the supply windings induce a voltage on to the secondary wires producing your 5000 volts. Florescent ballasts are transformers and you may find a specific one that produces that voltage. Http://www.dencosales.com/files/Download/Allanson%20EK%20Product%20Dimensions.pdf
This is a pdf from denco sales that fits your output voltage, but only at 30mA.

Helen asks…
What are 25 ways to protect my family and home from a torrential storm?
Detailed List please.
admin answers:
1) move *the act of packing and moving to a different location. If not possible, continue.
2) depending on your budget, some major re-modeling is in order.
3) install additional braces to your roof trusses.
4) Glue your roof…
(a)During a hurricane, the wind may almost seem to be ripping the roof off your home. So give your roof a bit of reinforcement. With some glue, you can increase your roof’s resistance to wind.
The Federal Alliance for Safe Home recommends you go to your local home improvement store and get premium flooring adhesive. Using a caulking gun, put a small bead of glue to the underside of your roof where the roof and the support beams meet. Be sure to look for an adhesive that has been tested and has a strong rating like APA AFG-01 ASTM D 3498.
5) insure your storm gutters are draining rain ample distance, peferably down hill from your home.
6) insure your storm gutters are free from leaves and other foreign debris.
7) waterproof your basement. You can do it yourself by consulting a sales associate at your local home improvement store. Or you can hire an outside company. Again, depends on your budget.
8) ensure your home is fall distance away from large trees or poles. Trees you can use a chain saw yourself and cut it to fall away from your house. Poles are more tricky to remove. You need to write your congress person and tell them that the utility pole on your property is causing cancer to your child. Then you need to adopt a girl and shave “most” of her hair off… Then get the news to have a heartfelt story on you and your plight. Then, the pole is moved…
9)Back up generators for emergency power. Generators are cheap and run on gas. You can get a decent one at your local home improvement store.
10)Vacuum sealer and large bags. Seal blankets and pillows and the like into these bags. You should vacuum seal the blankets as to keep spiders, mice and other “pests” out.
11) Large bags for your vacuum sealer.
12) sleeping bags for your vacuum sealer
13) invest in a sump pump incase the water comes into your basement.
14) replace your old windows. Newer windows come with an “act of god” warranty.
15) think about installing “impact resistant windows”
16) invest in a flash light that doesn’t require batteries (the one you shake “as seen on T.V.”)
17) invest in a radio that works on gyroscope
18) check the weight on your garage door. Many use the lightest material to save them and ultimately you costs.
19) have tarp handy for if when a hole is blown in your roof, you can patch it up when the eye of the storm is over you.
20) register for the next CCW class (carry concealed weapon). Check state and local laws…
21) practice at a shooting range after obtaining your CCW Permit. You never know when Martial Law will take over….
22) register for CPR courses. It may come in handy…
23)
(a) If you have furniture and other outdoor equipment on your patio or deck, bring them inside when strong weather threatens. Don’t forget trash cans, grills, toys, and potted plants. Keep them from becoming flying objects that can cause additional injury or damage during storms with high winds.
“You would be very surprised about what people don’t think about,” says Chapman-Henderson. “We saw garden gnomes wedged into palm trees. We saw an old record sliced into a tree. We saw sailboats in the tops of trees after Hurricane Andrew,” she said.
24) purchase blow up inner rafts, innertubes ect. Ect (and an air pump) You never know when you will need to float to the nearest shelter after a major storm.
25) go to www.myspace.com/therukiz

Your Questions About Wind Turbine Cost
Lizzie asks…
What’s your response to a wind turbine company marketing only in blue states?
Madison-Green Technologies, a startup firm in upstate, New York is currently working on something called the “Model 10” wind turbine, a device which is designed to be a low cost point of access for those who wish to get started with alternative energy. The wind turbine kits, which cost under $1000 are designed to produce 130 kilowatt-hours of electricity per month when placed in an area with exposure to a 10 mph prevailing wind. 130 kilowatt-hours is roughly 10% of the average American consumers electricity usage per month, and is closer to 20% of the average users tally in Northeastern states where air-conditioning usage is lower and many homes use heating-oil or natural gas furnaces.
In an interesting twist, the company founders are using the 2012 electoral map to focus their marketing efforts, and will focus on those states where President Obama won by the largest margin. “We know that just because we’re a green technology company that FOX News and Newsmax will do everything they can to convince conservatives that we’re evil incarnate,” said one company founder. If someone lives in a Red state and they want to purchase one of our units via our website they can but we aren’t going to waste our time developing any storefronts or looking for partnerships with contractors to install the units in any of the states where Romney won,” he continued.
What’s your response to green energy company like Madison-Green Technologies using the 2012 electoral map to focus their marketing efforts?
Alan, they said people can still purchase the units and they’ll ship to a red state, but people in those states are on their own from that point. They have to install it themselves or find their own contractor to do the work.
admin answers:
I don’t know if it’s such a smart marketing plan. Wouldn’t it make more sense to develop storefronts and partnerships in those areas of the country with exposure to a 10 MPH or greater prevailing wind? I think the pitch should differ in red and blue states, however. In a blue state saving money on your energy bill WHILE reducing carbon emissions that cause climate change AND putting contractors to work, which pumps money into the local economy, is a pitch that makes sense especially if there is also a local bank willing to provide affordable financing. In a red state you simply want to point out the cost savings, ease of financing and collateral benefits to the local economy.
That’s my response.

How do you measure windmill efficiency without using a generator?
Is there a formula I can use to convert the number of the windmill’s rotations into watts or some other measurement? I’m doing a science fair project about windmills and I don’t have a generator I can use to measure the amount of electricity produced. The only formula I found is watts = (Kh x number of disk rotations x 3600) / number of seconds, but I don’t have the Kh.
I’m really confused, please help!
admin answers:
Go look at www.awea.org for general info on turbines.
Unless you know the specific turbine manufacturer and model, it will be very difficult to relate turbine speed (in rpm) to power produced.
Besides, how do you expect to relate rotational speed to efficiency?
Efficiency is Output electrical power divided by Input wind power.
Perhaps you should look at the capacity factor of wind turbines, and the resulting relative cost of electric power as it relates to capacity factor.
